Apologies to the folks who've seen this before but Mark Handley has a  
relevant paper on deployment called "Why the Internet Only Just  
Works"[1].  It makes the case that when there is a shared perception  
that the need for change is dire new technologies can deploy very  
quickly.  CIDR is an example of where this perception existed.  IP  
Multicast, Mobile IP, quality of service, and ECN are examples where  
it didn't.

Based on this I'd say that if the folks who need to implement &  
deploy the technology share that perception of dire need, a ships-in- 
the-night deployment could work.
